Spectral analysis is the process of estimating the power spectrum (PS) of a signal from its time-domain representation.
(EV)method. These methods are best suited for line spectra — that is, spectra of sinusoidal signals — and are effective in the detection of sinusoids buried in noise, especially when the signal to noise ratios are low. The subspace methods do not yield true PSD estimates: they do not ...
Spectral analysis studies the frequency spectrum contained in discrete, uniformly sampled data. The Fourier transform is a tool that reveals frequency components of a time- or space-based signal by representing it in frequency space. The following table lists common quantities used to characterize and...

This, however, can add undesired artifacts to the spectrum and might lead to analysis errors. A better alternative is to use the Lomb-Scargle method, which works directly with the nonuniform samples and thus makes it unnecessary to resample or interpolate. The algorithm has been implemented in ...
